Spot Calculator
The spot spread calculator estimates profit from cross-exchange arbitrage on a real spot trade. The tool accounts for buy and sell prices, token quantity, and all fees — trading and transfer. The result shows the final profit in USD/USDT without any extra steps.
What is a spot spread calculator
The spot calculator is an online tool for pre-evaluating an arbitrage trade in the cryptocurrency market. Unlike the futures calculator, there is no leverage or funding rate here. The trader works with a real asset: buys a coin on one exchange and sells it on another.
Spread in spot trading is the difference between the buy price and the sell price of the same asset on different exchanges. For example, BTC costs 68,000 USDT on Exchange A and 68,600 USDT on Exchange B. The spread is 600 USDT, or about 0.88%. From this amount, you need to subtract fees for buying, selling, and transferring tokens. The calculator does this automatically.
The tool is suitable for calculating trades on any cryptocurrency pairs: BTC, ETH, USDT, and other tokens.
What data is needed for the calculation
To get an accurate result, you need to fill in seven fields. Three of them are required — the calculation won't run without them.
| Parameter | What to enter |
|---|---|
| Buy Price (Buy Exchange) | Current asset price in USDT on the exchange where the purchase is made |
| Tokens Bought | Position size in coins — this is how many will be bought and transferred |
| Buy Commission | Amount in USDT that the exchange will charge when executing the buy order |
| Transfer Commission | Cost of withdrawing tokens from the buy exchange to the sell exchange |
| Sell Price (Sell Exchange) | Current asset price in USDT on the exchange where the sale will be made |
| Tokens Sold | Number of tokens to be sold (accounting for transfer losses) |
| Sell Commission | Amount in USDT that the exchange will charge when executing the sell order |
Important! The fields "Buy Price", "Sell Price", "Tokens Bought", and "Tokens Sold" are required. The system cannot calculate the result without them.
How to calculate the spread
The calculation takes less than a minute. Steps:
- Open the online spread calculator on the page.
- Enter the asset buy price on the first exchange in USDT.
- Specify the number of tokens bought.
- Fill in the buy commission and transfer commission in USDT.
- Enter the sell price on the second exchange in USDT.
- Specify the number of tokens to sell — it may differ from the bought amount due to network fees.
- Fill in the sell commission.
After entering the data, the calculator instantly displays the results.
What the results show
The calculator outputs three final values.
| Metric | Description |
|---|---|
| Bought For (USDT) | Total cost of purchasing the asset on the first exchange |
| Sold For (USDT) | Revenue from selling the asset on the second exchange |
| Profit in USDT | Final profit or loss — the difference between revenue and costs |
If the profit is negative — the trade is unprofitable. Most likely, fees are eating up the entire spread. You need to find a pair with a wider price discrepancy or reduce the transfer fee by choosing a different network.
Spot arbitrage and risk management
The spot arbitrage strategy is considered less risky than futures. There is no liquidation threat, no funding impact. But risks still exist.
Key factors that affect trade results:
- Market volatility. While the token is being transferred between exchanges, the price can change. High volatility reduces or completely eliminates the spread.
- Transfer time. Some networks take from 10 minutes to several hours. During this time, quotes can shift.
- Network fee. For tokens on Ethereum, the transaction cost can exceed the entire potential profit. It's more profitable to use networks with low fees — BEP-20, TRC-20, and others.
- Liquidity volume. A market order for a large amount can move the price on a low-liquidity market. The calculation is based on the market rate at the time of data entry.
Important! Before opening a position, make sure the spread covers all fees with a margin of at least 0.3–0.5%. Otherwise, the trade may go negative due to slippage.
Tips for working with the spot calculator
To ensure accurate calculations, follow a few rules.
- Use up-to-date quotes. Exchange prices update every second. Data for calculations should be taken immediately before opening a position.
- Account for all fees. Don't forget about the network withdrawal fee — it depends on the chosen network and can vary significantly. An Ethereum transaction during peak hours costs more than the entire potential profit from a small trade.
- Check the number of tokens on the output. The "Sold For" field is not the same as "Bought For". The network withholds a portion of coins as a fee. Enter the exact amount that will arrive at the sell exchange.
- Compare multiple pairs. The calculator is free and works online without registration. You can quickly calculate several options and choose the trade with the best profit-to-risk ratio.
